We've been using quasi-Monte Carlo integration in a class here at
Cooper, and the discussion turned to parallelization. Some of my
classmates are going the MPI/cluster route, and I was thinking this
might be a good use of Plan 9's CSP style. The general idea I had
uses one point generator process, n function evaluation processes, and
a collection process that handles estimation &c.
I think I know how to structure this on a single multiprocessor
machine, but what about a cluster? Is there the equivalent of alts on
network connections?
If the question is unclear, I'll try again after I've gotten my
machine running the single computer form.

cec(8) muxes the keyboard and the network in a simple fashion.
/n/sources/contrib/quanstro/src/cec/mux.c. this could be written
with Chan so that one could alt on network messages.
